摘要：This paper discusses how to improve teaching of Mathematics in Brazilian schools, based on Seymour Papert’s Constructionism associated with Information Technology tools. Specifically, this work introduces the constructionist microworld, a digital environment where students are able to build their knowledge interactively, in this case, using dynamic mathematics software GeoGebra.
